No person may turn a vehicle at an intersection unless the vehicle
is in proper position upon the roadway or turn a vehicle to enter
a private road or driveway, or otherwise turn a vehicle from a direct
course or move right or left upon a roadway unless and until such
movement can be made with reasonable safety.
The driver of a vehicle intending to turn at an intersection
shall do so as follows:
A. Both the approach for a right turn and a right turn shall be made
as close as practical to the right-hand curb or edge of the roadway.
B. The driver of a vehicle intending to turn left at any intersection
shall approach the intersection in the extreme left-hand lane lawfully
available to traffic moving in the direction of travel of such vehicle,
and after entering the intersection, the left turn shall be made so
as to leave the intersection in a lane lawfully available to traffic
moving in such direction upon the roadway being entered. Whenever
practicable, the left turn shall be made in that portion of the intersection
to the left of the center of the intersection.
The City Council may cause official traffic-control devices
to be placed within or adjacent to intersections and thereby require
and direct that a different course from that specified in this article
be traveled by vehicles turning at an intersection, and when such
devices are so placed, no driver of a vehicle shall turn a vehicle
at an intersection other than as directed and required by such devices.
No vehicle shall be turned so as to proceed in the opposite
direction upon any curve, or upon the approach to, or near the crest
of a grade, where such vehicle cannot be seen by the driver of any
other vehicle approaching from either direction within 500 feet.
The electric turn signal device must be used to indicate an
intention to turn, change lanes or start from a parallel parked position
but must not be flashed on one side only on a parked or disabled vehicle
or flashed as a courtesy or "do pass" signal to operators of other
vehicles approaching from the rear. However, such signal devices may
be flashed simultaneously on both sides of a motor vehicle to indicate
the presence of a vehicular traffic hazard requiring unusual care
in approaching, overtaking and passing.
